ISSUES IN SOLUTION

We have proposed a curve fitting model using a least squares approach. Students may prefer other functions and other approaches.

If this is an initial curve fitting exercise students may start with a linear fit, but issues such as what does it mean to eventually have a negative length for a sound bite feedback to the students and they begin to propose models which stay non-negative.

The issue of whether or not the sound bite length will go to zero eventually occurs when students use a pure exponential, for example
f(t) = A Exp[ k t] without any added constant.
